Jacobsons Organs (Sense Organs) In Reptiles:
In Reptiles the “organs of Jacobson” are well developed sac like chambers. They lie below the nasal cavity and above the buccal cavity. Each organ is a blind pocket. It is lined with olfactory epithelium. Each sac opens into the buccal cavity through narrow duct.
The Jacobsons organs will develop as an outgrowth from the nasal cavity. The Jacobson’s organ get nerves from the oactory nerve and a branch from the trigeminal nerve. These organs test the smell of the food when it is taken into the buccal cavity.
